Frequency with which a philosopher brought up a goddess (5)
I believe the answer is:
freya
This clue might be a double definition.
'frequency with which a philosopher brought up a' is the first definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'goddess' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for freya that I've seen before include "Female" , "Norse love goddess" , "Norwegian goddess" .)
